if (402.5 - 285.7) / 5 = 80.5 then it is correct

I can see what you have done you found the value of the gradienr by 402.5 / 5 , this is wrong , the gradient is the change in y over the change it x

our initial value of y wasnt zero , it was 285.7 thus why you take the difference of the y's , then divide by the change in x

y= 23.36x + 285.7 // fairly sure thats the correct answer
